T0 all wwni, t''may concern.'

Be-it known that I, JAMES M. HoRToN, of

4the city of Albany, State of Newv York, have invented a Shank-Socket for use with `Anger- Handles, adapted to the service of angers of various sizes, whose shanksare necessarily I of -di'derentsizes, so that one handle may suflice for the service .of any number of angers; and I declare the following specification, with the drawings hereto attached as part of the saine, to be a full and complete description of my invention. Ii

Figure 1 represents in perspective the socket Fig. 2 is a view of-the socket'in plan as seen from below, with ille shank-grips removed. Fig. 3 is a vertical sectional view through the center of the socket,showing the shank of an anger fastened within the grips. section of the socket, show-ing the g'rips detached and exhibited separately.

Similar letters denote the saine paris of the apparatus.

H H, Fig. 1, is an auger-handle. (Shown in Ais a'mctal band surrounding its center,

andwhose lower part is formed into aprojecting cylinder, C, about one and a quarter.

On oppositeinches in diameter and length. sides ot' it a recess, a a, about v-threequarters of an inch wide and three sixteenths of'an -inch deep, is sunk andcontinned under and across the bottoni.4 The upper end of this recess terminates in a deeper recess, b b, within the lower portion of the band A.. This recess is intended to receive the jaws or grips B and D, the-formas of which are shown in perspeetivefin Figk 4. The upper ends of them are curved-to lie within the recesses b b and act ashinges, on which the can swing to and from tliecenter of the soc et. Their lower ends 'project from them so as to underlie'the cylinder'C, .theiredgesrwhich faoeeach other, beingcutiinto angnlarjaws, as shown.

Fig. 4 isa similar' Along'the central axis of the cylinder there 1S made a rectangular tapering bore, E, snlticient to receive the largestsized angel-shank is np near the handle, thelower part oi' Band-- D can swing out, as shown in Figs. 1 and 3, and receive between them and hold a large shank, S, or when the ring or nut is screwed down can hold a small shanln'tlins adapting itself to angers of various sizes.

In order to hold the shank i'roin vquitting the socket when the angnr is drawn upward,

a n/otch is made in one of the angular edges.

of the shank, as shown at e, Fig. 3, and the jawD, Fig. 4, is not cnt down tothe ldepth of its angle, but a portion of the metal is left to lie withinthe notch e.

This apparatus is 'especially intended for use with angers; but I intendits applicationas well to center-bits, or anyother analogous l boring machinery.`

What I claim as niy invention, and desire to secure by Letters Patent, is

The band A, with its projecting cylinder' C, having a'screw-thread cnt upon it, 'and having the recesses a and b formed thereinto receive the grips, the grips B and D, formed and fitted as described, the nut N, fitted t0 the screwthread ol the cylinder, the whole arrangedand combined substantially-v in the manner and furthe-purposes set .forth in the above specification.
